L’intensification des pratiques agricoles et la mobilisation des ressources naturelles dans La Pampa du Sud du Brésil

Southern Brazil, which has a good natural potential due to its sub-tropical climate and its favorable topography, is mainly dedicated to breeding and cultivating soybean, rice and corn. Like others in Brazil, this region is involved in the production of agricultural products for domestic and interna...
